Description

Technical Field

[0001] This utility model relates to the field of plastic recycling technology, specifically a plastic recycling granulator. Background Technology

[0002] Plastics are high molecular weight compounds formed by adding various additives to natural or synthetic resins through addition or condensation reactions. They have plasticity and wide applicability. Among them, plastic recycling granulators are devices that reprocess waste plastics into granular plastics, mainly used for plastic recycling and reuse.

[0003] The prior art disclosure number CN218659962U discloses a plastic recycling granulator, including a base, on which a frame plate is provided. A hot melt machine is provided on the frame plate to discharge the hot melted waste plastic into a conveying cylinder. The hot melted plastic is conveyed through the conveying cylinder to a processing frame for extrusion processing. Then, a cutting component is used to quickly cut and granulate the extruded plastic. At the same time, a cooling component cools the plastic to prevent it from softening too much and adhering to the extrusion plate and cutting component. The overall granulator has a simple structure and is easy to operate. It has a good integrated recycling and granulation effect, low cost, and is easy to maintain, resulting in better performance.

[0004] With the above configuration, the existing granulator uses a hot-melt machine to discharge the melted waste plastic into a conveying cylinder. The conveying cylinder then transports the melted plastic to a processing frame for extrusion. A cutting assembly then rapidly cuts and granulates the extruded plastic. Simultaneously, a cooling assembly cools the plastic to prevent it from becoming too soft and adhering to the extrusion plate and cutting assembly. The overall granulator has a simple structure, is easy to operate, provides good integrated recycling and granulation results, is low-cost, and easy to maintain, making it more practical. However, the existing granulator has the following drawbacks during operation:

[0005] In existing granulators, the first and second extrusion plates are prone to clogging after prolonged use. Uncooled plastic easily adheres to these plates, preventing quick disassembly of the mounting frame and hindering effective cleaning of the first and second extrusion plates. Additionally, the cutting blades wear down over time, making quick disassembly and replacement difficult, which affects plastic cutting and reduces the granulator's production efficiency. Utility Model Content

[0006] This utility model aims to provide a plastic recycling granulator, mainly to solve the technical problems existing in the prior art, such as the inability to quickly disassemble the mounting frame, which affects the cleaning of the first and second extrusion plates, and the inability to quickly replace the cutting blades, which affects the cutting efficiency of the cutting blades and reduces the production efficiency of the granulator.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A plastic recycling granulator includes a base, a mounting frame, a motor, and a turntable. The motor is fixedly connected to one side of the mounting frame, and the turntables are symmetrically rotatably connected to the inner wall of the mounting frame. The output shaft of the motor passes through the mounting frame and is fixedly connected to one of the turntables. Cutting blades are installed between the turntables. The bottom surface of the base has a mounting groove, and the mounting frame is installed inside the mounting groove. The base has a movable cavity inside, and a fixing component for fixing the mounting frame is installed inside the movable cavity.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When it is necessary to disassemble the mounting frame, first adjust the fixing component so that the fixing rod is disengaged from the fixing groove. Then pull the mounting frame down so that the mounting frame is disengaged from the mounting groove, thus completing the disassembly of the mounting frame. Then press the actuating block so that the snap-fit ​​cylinder is disengaged from the snap-fit ​​block, and then the cutting blade can be removed, thus completing the disassembly of the cutting blade.

[0011] 2. Beneficial effects:

[0012] Existing technology uses a hot-melt machine to discharge molten waste plastic into a conveyor cylinder, which then transports the molten plastic to a processing frame for extrusion. A cutting assembly then rapidly cuts and granulates the extruded plastic. Simultaneously, a cooling assembly cools the plastic to prevent it from becoming too soft and adhering to the extrusion plates and cutting assembly. The overall granulator has a simple structure, is easy to operate, offers good integrated recycling and granulation results, is low-cost, and easy to maintain, making it highly practical. However, after prolonged use, the first and second extrusion plates of existing granulators are prone to clogging. Uncooled plastic easily adheres to these plates, and the mounting frame cannot be quickly disassembled, hindering the proper functioning of the first and second extrusion plates. Effective cleaning is essential. After prolonged use, the cutting blades wear down, making quick disassembly and replacement difficult, affecting plastic cutting and reducing granulator efficiency. This solution addresses this issue by incorporating a fixed cavity, a first L-shaped plate, a second L-shaped plate, gears, toothed grooves, a fixed spring, a compression spring, a push block, a moving rod, a locking cylinder, and a locking block. During disassembly, rotating the gears compresses the first and second L-shaped plates, causing the fixed rod to disengage from the fixed groove. This allows the mounting frame to be removed for easy cleaning of the first and second extrusion plates. Pressing the push block disengages the locking cylinder from the locking block on the cutting blade, enabling quick blade replacement.

[0013] Preferably, the fixing assembly includes a first L-shaped plate and a second L-shaped plate, both of which are slidably connected to the inner wall of the movable cavity. The outer wall of the mounting frame has symmetrical fixing grooves. A fixing rod is fixedly connected to one side of each of the first and second L-shaped plates, passing through the mounting groove and inserting into it. A gear is rotatably connected to the inner wall of the movable cavity. Gear teeth are formed on opposite sides of the first and second L-shaped plates, meshing with the gear teeth. A fixing spring is fixedly connected to the inner wall of the movable cavity, and is fixedly connected to both the first and second L-shaped plates. A rotating rod is fixedly connected to one side of the gear, passing through and rotatably connecting to the base. By providing the fixing assembly, the mounting frame can be quickly fixed and disassembled.

[0014] Preferably, one side of the turntable has a movable groove and symmetrical sliding grooves. The movable groove and the sliding grooves are connected. A compression spring is fixed to the inner wall of the movable groove, and a pressing block is fixed to the other end of the compression spring. The pressing block is slidably connected to the movable groove. Symmetrical sliding rods are fixed to the outer wall of the pressing block, and the sliding rods are slidably connected to the sliding grooves. A locking cylinder is fixed to one side of the sliding rod away from the pressing block. Locking blocks are fixed to both ends of the cutting blade, and the locking blocks are inserted into the locking cylinders. By setting up the pressing block, sliding rods, and locking cylinders, the cutting blade can be easily disassembled, and severely worn blades can be quickly replaced, improving production efficiency.

[0015] Preferably, one side of the turntable has a groove, and a spring shaft is installed inside the groove. One end of the spring shaft is fixed with a retaining plate, which abuts against the push block. By setting the retaining plate, after the push block is pressed, the retaining plate abuts against the push block under the rebound force of the spring shaft, making it convenient to replace the cutting blade.

[0016] Preferably, a rotating block is fixed to the end of the rotating rod away from the gear, and the outer wall of the rotating block has anti-slip texture. By setting the rotating block, it is convenient to adjust the fixing components and facilitate the disassembly of the mounting frame.

[0017] Preferably, the end of the fixing rod that intersects with the fixing groove has a bevel. This facilitates the installation of the mounting block.

[0018] Preferably, rubber pads are fixed to the sides of the push block and the locking plate that come into contact with the fingers. This increases the friction between the fingers and the push block and the locking plate. Attached Figure Description
